woman turns off her tepeo zeb heat battery boiler as she leaves the house

A better boiler for a world without gas

A heat battery boiler is a simpler way to move away from gas, oil or LPG.

It charges when electricity is cheaper, stores that energy as heat, then delivers it through your existing central heating when you need it.

No outdoor unit. Minimal changes to your home. Familiar heating, with smarter technology behind it.

What is a heat battery boiler?

A heat battery boiler, like the tepeo ZEB, is a low carbon boiler that stores energy as heat for later, rather than relying on electricity only at the moment your home needs heating.

The ZEB charges a high-density ceramic core using electricity, then releases that stored heat through your existing radiators or underfloor heating when you need it.

Unlike a heat pump, it doesn’t need an outdoor unit. And unlike a standard electric boiler, it can charge ahead of time when electricity is cheaper – making it a practical and affordable way for suitable homes to move away from gas, oil or LPG.

See how the ZEB works

Switch from gas, oil or LPG without a major overhaul of your home.

We’ve made it as easy and quick as possible to move away from fossil fuel heating.

Seamlessly replace your existing boiler

The ZEB works with your existing pipework, radiators and underfloor heating. Installation can often be completed in just 1-2 days.

Make the most of cheaper electricity

Smart charging learns what your home needs, using your tariff, past energy use and local weather to automatically charge at the most effective times.

No outdoor unit needed

Everything is installed indoors, so you can move away from gas without giving up garden or outdoor space.

A practical move away from gas

Heat your home without burning fossil fuels, while keeping the familiar central heating experience you’re used to.

The future is electric.

Climate change is one of the biggest challenges we face, and heating our homes has an important part to play in tackling it.

That’s why we’re focused on helping more homes move away from fossil fuels and towards cleaner electricity. We believe the future is electric — and we’re building practical heating technology to help make that transition possible.

We want to make switching to cleaner heating more accessible. That’s why we’re currently offering £2,500 off the cost of a ZEB through our Early Grant Match – bringing forward the support soon to be available through the government’s Boiler Upgrade Scheme.

It’s our way of helping more households make the move away from fossil fuels sooner.

Could a heat battery boiler work in your home?

The ZEB is designed for suitable homes with wet central heating and can be particularly useful if you want to move away from fossil fuels without installing an outdoor unit or carrying out a larger heating retrofit.

It typically works best where you have:

A wet central heating system

Radiators or underfloor heating that the ZEB can connect to.

Space for the ZEB

Suitable indoor space. The ZEB is versatile and can be installed in a wide variety of indoor locations.

Suitable heat demand

Your home's estimated annual heating and hot water demand within the ZEB's suitable range.

A smart meter and suitable tariff

Access to a smart meter and a time-of-use tariff so the ZEB can make the most of cheaper off-peak electricity.
